Results of the Ontology Alignment Evaluation Initiative 2021 [PDF]

, 2021
The Ontology Alignment Evaluation Initiative (OAEI) aims at comparing ontology matching systems on precisely defined test cases. These test cases can be based on ontologies of different levels of complexity and use different evaluation modalities (e.g., blind evaluation, open evaluation, or consensus).

Random Noise Suppression Method for Inertial Sensors Based on Complexing an AR Model and Adaptive SRUKF Kalman Filter under the PINS Alignment on a Stationary Platform

Известия высших учебных заведений России: Радиоэлектроника, 2023
Introduction. In the gyrocompassing mode, the initial heading angle of a platformless inertial navigation system (PINS) is determined based on the data obtained from accelerometers and gyroscopes that measure the projections of the gravitational ...

Initial alignment of point clouds using motors [PDF]

Proceedings of the Computer Graphics International Conference, 2017
This paper presents an approach for initial alignment or coarse registration of a partial 3D point cloud of objects. The method is based on computing the centroid of the points in the point cloud, and a line derived from the surface normals. This approach uses conformal geometric algebra and non-linear least squares optimization to achieve the results.
